摘要:
A method for synthesizing beta-sulfanyl ketones via a tandem rearrangement and conjugate addition reaction has been developed. This methodology provides access to a range of beta-sulfanyl ketones through the rearrangement of propargyl alcohols to the corresponding enones followed by the conjugate addition of unactivated thiols. The one-pot, tandem transformation is catalyzed by ReOCl3(OPPh3)(S(CH3)(2)) affording aryl and alkyl beta-sulfanyl ketones in good to excellent yield. (C) 2012 Elsevier Ltd. All rights reserved.
